AUGUSTE ROLLAND AD EDMOND LAMBERT OONTN'CK, OF PARIS, FRANCE.

ARGAND LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 366,509, dated July 12, 1887.

Application filed September 18, 1886. Serial No. 213,881. (No model.) Patented in France December 18, 1884, No. 166,004; in Germany October Q3, 1885; in England October 23, 1885, No. 1Q,7'27, and in Belgium October24, 1835, No. 70,610.

To all whom it may concern.-

Beit known that we, AUoUsrn ROLLAND and EDMOND LAMBERT GoiviNoK, citizens of the Republic of France, residing at Paris, in

the said Republic, have invented certain new and useful Improvements in Argand or Circular Burners llor Burning Petroleum and Other Liquids, of which the following is a specification, reference being had therein to the acio companying drawings.

Our invention relates to Argand or circular burners adapted for lamps in which petroleum or other oil is used; and the novelty consists, in general in the detail of construction relating i 5 to means for 'aising the wick and for preventing the oozing of the oil toward the outside, and ofthe chimney-carrier, and their combinations, all as will now be more fully described, as well as stated in the claims.

The accompanying drawings represent our invention in all its details.

Figure 1 is a vertical section drawn on the aXis ot' the burner. Fig. 2 is a plan on line y y, Fig. 1. Fig. 3 is a. side view of the wicktube; Fig. 4, a vertical central section on a plane passing through the air-opening. Fig. 5 is an under side View of the external tube supporting the pinions and the chimney-hold` er, taken on line y y, Fig. 4. Fig. 6 is an 3o under side View of the same tube, allowing a pinion to be seen in the place it occupies in the burner. Fig. 7 is an elevation of the pinion which adjusts the wick. Fig. S is a plan view of the ring carrying the grooves. Fig. 9

is a vertical central section, being the same View as in Fig. l, enlarged.

The burner is furnished with the ordinary collar, a, for sealing, carrying at the interior a conical screw-ring7 b, for the purpose above 4o indicated, or simply a screw-ring, c, capable of being soldered to the body ot' the lamp. Above the collar is a base, d, soldered to the burner, which can be screwed on the collar or the body of the lamp. It carries inside a ring,

e, with a 'Iiange or brim at its upper part to prevent the oozing of the petroleum.

On the bottom of revolving basket f is soldered the ring g, provided with helical-like grooves formed therein, and with the collar 7L,

5o to retain at the lower part ol' the burner the petroleum which would ooze around the piliions. This collar turns in the circular opening of ring d, thus serving as a pivot for the basket. rlhe teeth ofthe pinions 'i engage in the grooves, so that they revolve when the basketfis turned. These pinions are held in position by a stampedout piece, Z, in iorm of a conical tube, and provided with the projection m perpendicular to its axis, and carrying three supports, n,(see Figs. 4, 5, and 6,)wherein the axles of the pinions are lodged. This tube is soldered to t-he burner by its lower part, and is concentric tothe Wick-tube p, the triangular opening r of which gives passage to the inte` rior air-current. The excess of oil will iind exit through the holes fr, near the lower end.

The chimney-holder, which can be removed when required, is composed ofa ring, s, made in one piece and bent in the form shown in Figs. l and 9. It has inside ribs t, which, projecting inward toward the tube l, serve to clamp the chimney in place. At the same time the spaces u, between the ribs t, allow a flow of air and for the oozing petroleum. The upper external and outer part, o, ot' this chimney-holder may be connected to the lower and inner part, s, in any ordinary way or manner.

Vith the burner constructed in the above manner, in raising the wick it is only neces` sary to turn the basket to the right.; and to lower it, it is turned to the left.

Having now particularly described oursaid invention, and in what manner the same is to be constructed, we declare that what we claim 1S- 1. The combination, with an Argand lampburner, ot" the revolving basketf, having scoured thereto the ring g, provided with helical grooves, with the pinion i, the conical tube l, and the wick-tube p,substantia11 y as described.

2. The combination, with an Argand lampburner, ot' the conical tube Z, and the projection m, the support n, the pinion t', thc grooved ring g, and a basket, f, substantially as described.

3. Thecombination, with an Argand burner ICO 4. The combination, with'an Argand lamp- UcombinedWith/the conical tube Z, and the Wickburner, of the revolving basket f, and the raising mechanism constructed as shown, all' grooved ring g, to which it is secured, the tube substantially as described.
